APPARATUS FOR SINKING DISK ANCHORS.

SPECIFICATION forming part of Letters Patent No. 453,712, dated June 9,1891.

Application filed December 8, 1890. Serial No. 374,000. (No model.)

To all whom it may concern.-

Be it known that I, JOHN IV. NIER, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in and a new Method ofand Apparatus for SinkingDiskAnchors; and

I do declare the following to be a full, clear, and.

exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanyingdrawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention has relation to a new method of and apparatus for sinkingobjects in the banks or beds of rivers or water-ways; and the object isto provide a method of and apparatus for sinking anchors, such as areused for anchoring brush mattress when it is used for revettingriver-banks and similar places.

My invention therefore consists in the novel construction of the partsand their combination, as will be hereinafter fully described, andparticularly pointed out in the claims.

I have fully illustrated my invention in the accompanying drawings,wherein- Figure 1 is a view of the harpoon, showing the formation of itsupper end. Fig. 2 is a view of the harpoon, showing the formation of itslower end. Fig. 3 is a view of a section through Fig. 2 on the line 771.m. Fig. 4 is a view of a section through Fig. 2 on the line 019.

Referring now to the illustrations, wherein like parts are designated bythe same letters of reference, A and B designate hollow supply-pipes ofthe usual construction, running parallel with each other, except attheir upper ends, where they diverge or spread out to form asemicircularshaped elbow, which is provided with suitable joints, thebushings b b, and an opening E, provided for the attachment of a rubberhose to allow water to be forced through said pipes for the well-knownpurpose of boring by water-jet. Said supply-pipes are held firmlytogether by means of metal collars O O, placed at suitable distancesapart, and are also firmly Welded to the shield or pointed oval plate F.Shield F is provided with a lip Z and a concave or hollow disk G, madein a circular form. '17. a designate small openings provided on theupper surface of the pipes A and B. D designates a rod, which is securedbetween said pipes, being provided with a tongue-shaped clamp II at itslower end and a spiral spring e running around the rod, a cam 0 justabove said spring, and a cam-handle (Z for operating said cam to adjustthe tongue-shaped clamp II to raise or lower it, as desired, all forminga device which I call a harpoon.

The circular-shaped concave disk or groove referred to on the harpoon isfor the purpose of receiving a circular disk or mushroom anchor; but itwill be readily seen that this disk or groove may be easily changed toany desired shape to receive any shaped anchors that may be thought bestto use.

The operation is as follows, and the method which I claim is herebydescribed: Vhen a circular disk or mushroom anchor is used, it is placedin the circular disk or groove on the harpoon, which is hollowed orconcaved to receive it. The anchor having been fitted into said hollowdisk, the tongue-shaped clamp at the end of the rod D is pushed downover the upper edge of the anchor by an operation of the cam-handle dupon the cam c to hold said anchor in place in the hollow disk, saidanchor being at this point in a perpendicular or upright position,similar to the harpoon itself, which is then lowered into the water,pointed end downward, which, by means of water forced through thesupply-pipes forming a water-jet, bores a hole in the earth. When at thedesired depth, the clamp holding the anchor in the hollow disk is drawnup and made to release the anchor by an operation of the cam-handle clon the cam c. The pressure of the water from the small jets a n, actingon one side of the anchor after its release, causes the anchor to changefrom a perpendicular to a horizontal position, with its upper or fiatside upward. The harpoon then being withdrawn, the sand, mud, and gravelclose in and fill up the hole or opening, leaving the %Il Cll10l'securely buried in the bank or river- Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

1. In an anchor-sinking apparatus, the combination of the supply-pipes Aand B, provided with small openings n a, a large opening E,

and bushings b b, and the oval-shaped pointed shieldor plate F, bearingthe hollow disk G Y and lip Z, and the rod D, provided with the clamp H,spring 6, cam c, and cam-handle cl, said pipes and rod being fastenedtogether by the collar C, all substantially as described, and for thepurpose specified.

2. In an anchor-sinking apparatus, the combin ation of the rod D,provided with the clamp H, spring 6, cam c, and cam-handle d, with thesupply-pipes A and 13, provided With the openings E and n n and thebushings b b, and the oval-shaped shield or plate F, provided with "thehollow or grooved surface G and the lip Z, said rod and pipes beingfastened together by metal collars placed atsuitable distances from eachother, all substantially as described, and for the purpose specified.

3. An anchor-sinking apparatus in the form of a harpoon-shaped device,composed of the following parts, viz: two metal supply-pipes of ordinaryconstruction diverging outward at their upper parts to form asemicircularshaped elbow, said pipes being provided With small openingsat n and bushings b b, and a large opening E, provided with suitablemeans for attaching to a rubber hose or Waterpipe, their lower endsbeing welded to a pointed oval-shaped shield, which is provided with acircular grooved surface G and a lip Z, and a rod D, provided with theclamp H, spring 6, earn 0, and-caIn-handle d for adj usting the clamp H,all substan tially as described, and for the purpose specified.

4. In an anchor-sinking apparatus, the combination of supply-pipes A andB, provided with a suitable opening at their junction for attaching anordinary hose or water-pipe, and smaller openings at 'n and bushings bb, with an oval-shaped shield or plate pointed at its or groove G and alip Z for holding or receiving a circular disk or mushroom anchor, and arod D, provided with. the clamp H and a suitable spring, cam, andcam-handle for adjusting said clamp, all substantially as described, andfor the purpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.
